4. PLC Development Board
This chapter explains the key features of the CY3274 development board.
4.1 Board Details
The key features of the CY3274 development board are:
■
User friendly PLC Control Panel application
■
CY8CPLC20-OCD – 100-pin TQFP on-chip debug (OCD) device that allows quick design and
debug of a PLC application.
The CY8CPLC20 100-pin TQFP is available for debug purpose only. For production quantities,
CY8CPLC20 is available in 28-pin SSOP and 48-pin QFN packages.
■
Chip power supply derived from 110 V to 240 V AC
■
User configurable general purpose LEDs
■
General purpose 8-position DIP switch
■
On board surge protection and isolation circuit
■
RJ45 connector to use ICE debugger
■
RS232 COM port for communication
■
Header to attach the LCD card
■
I 2 C header for communicating to external device
■
ISSP header for programming the CY8CPLC20

4.2 CY3274 PLC Development Board Functional Overview
The CY3274 PLC development board is designed as a product development platform for low
bandwidth (up to 2400 bps) powerline communication.
The user-written application running on the CY8CPLC20 generates the data. The PLC core
encapsulates this data into a PLC network packet. The FSK modem then modulates this packet and
the coupling circuitry incorporates the resulting sinusoidal waveform on to the existing waveform on
the high voltage bus.
